Polyaluminium Chloride Description
Polyaluminium chloride (polyaluminium chloride/poly aluminium chloride/pac for water treatment)
It is high-efficient ,cheap and nontoxic inorganic high molecular compound .It's easily soluble in water.
In the hydrolytic process ,it is accompanied with the chemical processes such as
electrochemistry ,coagulation,absorption and precipitation. The product has the features including
wide applicable range of PH value ,large granule ,and quick speed in sedimentation .It's widely used
in treating the drinking water, sewage and industrial waste water.

Polyaluminium Chloride Production Process
1. Roller drying process:
Alum purity around 28%, water insoluble content high,most used in waste water treatment.
2.Spray drying process:
2.1 yellow color powder:
Alum purity can reach to 29%-31%, water insoluble content low, dissolved fast, used in drinking water treatment
2.2 white color powder:
Alum purity can reach to 29%-31%, water insoluble content low, dissolved fast, used in drinking water treatment, also can be used in paper production to increase the paper’s tension and whiteness
